Answer:
Determine if each statement is always, sometimes, or never true.
1. Parallel lines are
coplanar: Always true
2. Perpendicular lines are
coplanar: Always true
3. Distance around an unmarked circle can be measured: Never true
Explanation:
When we are say that lines are coplanar, this means that those lines happen to be or lie in the same plane , a flat surface or a 3- dimensional surface.
Co planar lines may or may not intersect with one another.
Parallel lines and Perpendicular lines are coplanar lines because they are found to be in the same plane. One of their differences is Parallel lines do not intersect with one another while Perpendicular lines intersect with one another.
Hence the statements:
Parallel lines and Perpendicular lines are coplanar is ALWAYS TRUE
Distance around an unmarked circle can be measured. This statement is never true
This is because a circle has to be marked in other to be able to measure it's distance properly. A marked circle will have its diameter and the diameter of a circle is also known as the distance around a circle.
